The Correct Option is

Solution and Explanation

Step 1: Concept
Faraday's Law: $e = \frac{\Delta \Phi}{\Delta t}$.

Step 2: Meaning

Change in flux $\Delta \Phi = e \times \Delta t$.

Step 3: Analysis

$\Delta \Phi = 2 \text{ V} \times 6 \text{ s} = 12$ Wb.

Step 4: Conclusion

The change in flux is 12 Wb.
Final Answer: (E)
